I take back my earlier post...Dr. Kill is right. If you think it matters...then it matters.

Now you dang guys got me to thinking...LOL...

Depending on the length of those bad boys.... you might be close to underspined. Depends on your head weight too. Fixed broadheads on the 400 at that weight are tricky if you're shooting a 125 head or bigger. They may have done you a favor.[8D]

I'm no bow technician by any stretch, but I think it matters. I had one particular bow shop wizard making arrows for me when I first got into archery, and he never built any two batches of arrows the same length. I'd bring him an arrow from the last batch, and get a new batch of yet a new length. At 1/8" the arrows still flew okay, but at 1/4" shorter, those arrows hit 6" high at 20 yards with broadheads attached. One arrow in that bunch I called my Randy Johnson slider arrow, because it broke about 9 inches down and right. You could see the darn thing turn about halfway to the target. (I've never before or since seen anything like it.)

I can't really explain why this was true, but I assure you it happened. One thing I do know, my bow was absolutely properly tuned. P.S. That bow shop wizard is now out of business.

Maybe I'm not a good enough shooter, but it hasn't mattered to me. I was out shooting broadheads last night at 60 yds. Four arrows were 31" and two were 30". They were all hitting a paper plate whenever I held right and released right.

That being said, when I'm hunting real critters I'll be shooting identical length shafts.
